Introduction
Toki Pona is a constructed language that Sonja Lang created in 2001 and documented in her book "Toki Pona: The Language of Good" (2014). It has exactly 120 official words. The design goal is minimalism: Lang wanted a language that simplifies thought by reducing everything to basic elements. Type a message above and the tool looks up each English word in a Toki Pona vocabulary dictionary, outputting the Toki Pona equivalent. Switch to decode mode to reverse the lookup. Unknown words pass through unchanged. All processing runs in your browser.

How this tool works
The translator splits your input into tokens using a regex that separates letter sequences from non-letter characters. Each word token is lowercased and looked up in a dictionary. In English-to-Toki Pona mode, the dictionary maps English words like "good" to "pona" and "person" to "jan". In Toki Pona-to-English mode, the reverse lookup runs. Words not found in the dictionary pass through unchanged. Non-word tokens (spaces, punctuation, line breaks) are preserved exactly. The mode setting syncs to a URL query parameter, so you can share a link that preserves your configuration.
How the Toki Pona language works
Sonja Lang created Toki Pona in 2001 and published the definitive reference in her book Toki Pona: The Language of Good (2014). According to the Wikipedia article on Toki Pona, Lang designed the language around minimalism and Daoist philosophy. The name "Toki Pona" means "good language" or "simple language" in the language itself. Lang is a Canadian linguist and translator who also works on Esperanto projects. The Wikipedia article on Sonja Lang notes that she drew inspiration from Daoism and the Sapir-Whorf hypothesis, which proposes that language shapes thought.
The language has 120 official words. The official site tokipona.org hosts lessons and community resources. Each word carries a broad meaning that shifts with context. The word "pona" can mean "good", "simple", "friendly", or "to fix" depending on its grammatical role. This polysemy is intentional. Lang wanted speakers to focus on the core idea behind each concept rather than splitting hairs between near-synonyms.
Toki Pona grammar is intentionally simple. Sentences follow a subject-predicate structure marked by the particle "li". The particle "e" marks direct objects. The particle "la" sets context. There are no tenses or plural markers. Numbers beyond two are expressed by compounding: "tu" means two, "tu tu" means four. The community has grown since 2001, with speakers on every continent. A 2021 survey by the Toki Pona community identified several hundred active speakers. The language has been featured in academic linguistics conferences and conlang publications.

Real-world examples
Translating a greeting
A user types "hello person" in English-to-Toki Pona mode. The tool looks up "hello" and finds "toki", then "person" and finds "jan". The output reads "toki jan". This is a standard Toki Pona greeting that translates literally as "person language" or "communicating with a person". The user copies the output and uses it in a Toki Pona chat group.
Describing the weather
Someone wants to say "the sun is warm" in Toki Pona. They type "sun warm" and get "suno seli". The word "suno" means sun or light, and "seli" means fire, heat, or warm. In a full Toki Pona sentence this would be "suno li seli", with the particle "li" marking the predicate. The tool does not add grammatical particles, so the user adds "li" manually to form a complete sentence.
Decoding a Toki Pona phrase
A learner encounters the phrase "pona tawa mi" in a Toki Pona forum. They paste it into Toki Pona-to-English mode. The tool looks up "pona" and finds "good", "tawa" and finds "to", and "mi" and finds "I". The output reads "good to I". The learner recognizes this as the Toki Pona way of saying "good to me" or "it is good for me", which is a common expression of thanks.

Limitations or considerations
This tool performs word-level dictionary lookup, not full grammatical translation. Toki Pona has its own grammar with particles like "li", "e", "la", and "pi" that this tool does not add automatically. The vocabulary covers all 120 official words from Lang's 2014 book. Words outside the dictionary pass through unchanged. Each Toki Pona word has a broad meaning that shifts with context, so the English glosses in the dictionary are simplified. A full translation requires understanding Toki Pona grammar and choosing the right interpretation for each word in context. This is a vocabulary reference, not a full machine translation system. For other constructed language tools, try the Minionese translator, the Simlish translator, the Na'vi translator, or the Dothraki and Valyrian translator.
Frequently asked questions
Who created Toki Pona?
Sonja Lang created Toki Pona in 2001. She published the definitive reference in her book "Toki Pona: The Language of Good" in 2014. Lang is a Canadian linguist who drew inspiration from Daoism and the Sapir-Whorf hypothesis. She designed the language to have only 120 words and a simple grammar, making it possible to learn in a matter of days.
How many words does Toki Pona have?
Toki Pona has 120 official words. This tool includes all of them in its dictionary. The small vocabulary is intentional. Lang wanted speakers to combine basic words to express complex ideas rather than memorizing thousands of terms. For example, "alcohol" is expressed as "telo nasa" (crazy water), and "car" is "tomo tawa" (moving room).
Does this tool translate full Toki Pona sentences?
No. This tool performs word-level dictionary lookup. It matches each English word to its Toki Pona equivalent from the 120-word dictionary. Toki Pona has its own grammar with particles like "li", "e", "la", and "pi" that this tool does not add automatically. You need to learn the grammar separately and construct sentences by hand. The tool is a vocabulary reference, not a full machine translation system.
Is Toki Pona a real language?
Toki Pona is a constructed language, or conlang. It was designed by one person, Sonja Lang, rather than evolving naturally. However, it has a real community of speakers who use it for communication. Unlike most conlangs, Toki Pona was not created for a fictional world. Lang designed it as a real language for real use, inspired by the idea that a small vocabulary can change how you think.
Why do some English words not translate?
Toki Pona has only 120 words. Many English concepts do not have a direct equivalent. Instead, Toki Pona speakers combine existing words to describe new concepts. For example, there is no single word for "friend". A speaker would say "jan pona", which means "good person". This tool looks up single words, so compound expressions like "jan pona" will not appear automatically. You need to construct them yourself using the vocabulary table.
Conclusion
The Toki Pona translator converts English text to and from the 120-word constructed language Sonja Lang created in 2001. Type your message, switch modes, and copy the output.
